For those of you getting back into Oblivion (or those who’ve never left!), here’s a little tip to make your modding more productive.

I always used to take a lot of care which files from which mods I was overwriting, and in what order, using Oblivion Mod Manager (OBMM). If you installed the wrong mod last, it could overwrite changes from who-knows-what-other-mods. Wrye Bash and BAIN (Bash Installers) helps out a lot here–you don’t have to worry about the order in which you install mods, as BAIN tracks all files from all mods and makes sure higher priority ones take precedence. If you uninstall the higher priority mod, BAIN will automatically extract the now-missing files from the next mod in line that uses them.

But what about mods that replace original game files? If you ever want to go back to the original file(s), or uninstall the mod, you’ll need to get the files from a backup, or potentially even reinstall the game. This can be a huge annoyance, especially when you don’t know which files were original and which were put there by a mod.

BAIN to the rescue again! Thanks to Bash Installers, you can protect your original game files the same way your other mod files are protected. Here’s an example to show you how:

1. In your Bash Installers folder (usually right next to the Oblivion game folder), create a new subdirectory named “Bethesda Default Videos 1.0″ (or you can omit a version number, or use the game’s version number–whatever you prefer).
2. Under this new folder, create a new subdirectory named “Videos”
3. Go to your Oblivion directory, then to Data\Videos. Copy the following videos and paste them in the “Videos” folder you just created:
   2k games.bik
   bethesda softworks HD720p.bik
   CreditsMenu.bik
   game studios.bik
   Map loop.bik
   Oblivion iv logo.bik
   Oblivion Legal.bik
   OblivionIntro.bik
   OblivionOutro.bik
4. The mentioned .bik files should now exist in both the Oblivion Data directory as well as the Bash Installer directory you created.
5. Open Wrye Bash and go to the Installers tab.
6. At (or toward) the top, you should see a mod named ‘Bethesda Default Videos 1.0′ (or whatever name you chose). Right-click the mod and choose Pack to Archive. Leave the default name, and choose whether or not to use Solid Compression (I chose not to).
7. When it’s finished, right-click the project again and choose Delete.
8. Now scroll down and look in the mod list for ‘Bethesda Default Videos 1.0.7z’ (or the name you chose). It should appear green but not actually be installed.
9. Right-click it, and choose ‘Move To…’ and move it to position number 1. This will allow any other mod to overwrite these videos.
10. Right-click it and choose ‘Install’. This will re-extract the same identical video files over the existing ones in your Oblivion Data directory. No changes will be made–the files are exactly the same, and you will notice no difference in the game.

It seems like a lot of steps for a little benefit, but it really took under a minute to perform this whole process, and the best is yet to come.

What’s the big deal, you ask? Well, now you can feel free to install any mod which replaces the original video files. When you install a mod which does, you’ll notice it will list a Conflict with ‘Bethesda Default Videos 1.0′. No worries, you will see in the Conflicts tab that the mod has a higher priority and will overwrite the existing video.

The best part comes when you decide to uninstall that same mod. When you uninstall the mod through BAIN, it will delete the mod’s new video files, and will extract the original videos from Bethesda Default Videos 1.0 automatically in their place.

No missing files, no hunting through backups or reinstalling the game, and no needing to worry about the original files ever again. I’ve used the same trick for most of the files in my Data directory–Knights of the Nine and all of the DLC are excellent choices because there are so many mods that replace the original ESPs.

While I haven’t taken the time to do so, in theory you could go so far as to BAIN-ify the entire Data directory from a patched (but otherwise clean) Oblivion install and place the installer at position 1 in BAIN. Activate it (I know, it probably takes forever), then you will know when any mod overwrites original files, and those files will be restored whenever any mod that replaced them is uninstalled.

Now that’s automation!
